SunTouch UnderFloor Installation Manual
NEVER
cut the mat, or remove the foil radiator, or modify the mat in any way. The mat must
remain intact. However, the power leads may be cut shorter, if necessary, but never
removed completely.
NEVER
leave the mat rolled up or bunched in the joist bay. Make sure the mat is completely
unrolled and is installed completely flat.
NEVER
attempt to repair the mat if it is damaged. Call the factory for instructions.
NEVER
install one mat on top of another or overlap the mat onto itself. Doing so will cause
dangerous overheating.
NEVER
forget to install the floor sensor.
NEVER
remove the nameplate label.
NEVER
allow metal objects such as staples, metal pipes, ductwork, or straps to remain in contact with the foil radiator of the mat.
NEVER
staple closer than 1/4” from the heating wire.
NEVER
install the mat closer than 2” from the subfloor.
NEVER
install the mat closer than 8” from the edges of outlet boxes and junction boxes used to mount surface lighting fixtures.
NEVER
run mats across joists.
NEVER
insulate below the mat with greater than R-19, and no greater than R-11 total on top of the subfloor, including all floor coverings,
rugs, and other items placed on top.
ALWAYS
enter mat and sensor resistance readings in the Mat and Sensor Resistance Log (see page 5) before, during, and after the
installation process.
ALWAYS
pay close attention to the voltage and amperage requirements of the breaker, the control, and the mat. For instance, do not
supply 240 VAC to 120-VAC mats or controls.
ALWAYS
make sure all electrical work is done by qualified persons in accordance with local building and electrical codes, Section 62 of
CEC Part I, and the National Electrical Code (NEC), especially Article 424, Part IX of the NEC, ANSI/NFPA 70.
ALWAYS
use copper only as supply conductors.
ALWAYS
affix the warning label (included with this manual) to the control or other location where it is easily noticed in the area
containing the mat.
ALWAYS
seek help if a problem arises. If ever in doubt about the correct installation procedure to follow, or if the product appears to be
damaged, the factory must be contacted before proceeding with the installation.
